Do you see the trigger pulses in your msd review data file?

In their defense, they benched tested my grid and distributor in their rig and it worked perfectly.

I don't see any trigger pulses. only see the rev limiter coming on. It starts about the rpm that I have my shift lite set to. I aslo see short spikes on the shift lite graph. I have launch delay set out and shift delay. This is something new. It has worked before. Started acting up in eliminations last weekend and got worse every round
